The software Microsoft.Windows.Vista.Local.Activation.Server-MelindaGates lets users spoof that KMS process, allowing them to activate copies of the enterprise editions of Vista, its creators say. The hacked download is available online on file sharing sites.
Microsoft's official KMS offering is available to customers with 25 or more computers running Vista. The machines activate the software by connecting to the KMS server, and must reactivate every six months.
The MelindaGates hack allows users to download a VMware image of a KMS server which activates Windows Vista Business/Enterprise edition, its creators claim.
Vista is the first Windows operating system that requires volume users to activate each product. The new activation processes are aimed at reducing piracy.
